Question 4. (20 point, 10 points each) Consider the B+ tree index of order d 2 shown below. Assume the left order is for and the right order is for If you can borrow from both siblings, choose the right sibling. Answer these question:s Root 50 73 85 8 18324o 256810*18*27 32 39 73 80* 41 45* 52 58 91 99* a) Show the B+ tree after inserting the data entry with key 7 into the original tree. b) Show...
In the B + tree given below, every node must contain at least 2 key values (except the root) but never more than 4 key values. a. Diagram the top tree after the index value [50] is deleted. b. Diagram the bottom tree after the index value [38] is added.
Question 3. (25 points) Consider the B+ tree index shown below. Each intermediate node can hold up to five pointers and four key values. Each leaf can hold up to four records, and leaf nodes are doubly linked as usual, although these links are not shown in the figure. If you can borrow from or merge with both siblings, choose the right sibling. Answer the following questions 3080 I1 35425065 9098 12 68 69 70 79 98 99 1001105 30...
When using an empty 2-3 B+tree and inserting 9,7,3,8,5,15,12 Otrue false - the root node would be 7 with 2 children O true alse - the tree will have 3 levels true false - the root node will contain a 5 true false - the rightmost leaf node will contain 12 and 15
Consider the B+ tree shown in the following as an original tree. 73 85 1 2 5 6 8 1 32 39 41 45 52 58 73 91 99 Answer the following questions: 1) (2 marks) There are currently 18 records in this tree. How many additional records could be added to this tree without changing its height (give the maximum possible number)? (3 marks) Show the B+ tree after inserting a data entry with key 3 into the original...
[Index structure: B+ tree and B tree] (b). B+ tree index structure is said to be an improvement of B tree index structure. The most important distinction between them is that data record pointers exist in both internal and leaf nodes (i.e., blocks) for a B tree whereas only in the leaf nodes for a B+ tree. Explain why this distinction would make B+ tree a more efficient structure (in terms of index search speed) overall than a B tree...
Fig. 1 illustrates a red-black tree, where a thick circle represents a black data-bearing node, a thin circle represents a red data-bearing node, and a thick rectangle represents a black nil node. In your work, you have to write black near a black node and write red near a red node to indicate the colors. Alternatively, you may use a rectangle to represent a black node, and use a circle to represent a red node. - Draw the resulting red-black...
5. Draw the structure of B+ tree index with 3 levels from root to leaves when Index Blocking factor is 3, and the maximum fill factor is 100%. That is, the max number of Keys per Node = 3. Show the structure of each node in the B+ tree with the keys and (block) pointers as specific as possible where 3 keys in the root node are denoted as K-1, Ki, Ki+1.
QUESTION 1 In a tree, a ____ is a node with successor nodes. root child descendent parent sibling QUESTION 2 In a tree, the ____ is a measure of the distance from a node to the root. count degree branch height level QUESTION 3 Which of the following is not a characteristic of a binary search tree? Each node has zero, one, or two successors. The preorder traversal processes the node first, then the left subtree, and then the right...
Consider the B+ tree index shown in Figure 1. Each intermediate node can hold up to five pointers and four key values. Each leaf can hold up to four records, and leaf nodes are doubly linked as usual, although these links are not shown in the figure. Answer the following questions.
